Parsing Out Custom Tags - n00b Question

interactive

Alright I'm sure this is a rather n00bie question, but I've been searching and searching for the best/easiest way to do what I'm doing.

Here's what I'm doing:
I'm working on a template system. I've got most of it sorted out, the problem is I need to 'pull' tags off of the page.

Here's an example page:

<HTML>
 <HEAD>
  <TITLE>{&PAGE_TITLE&}</TITLE>
 </HEAD>
 <BODY TOPMARGIN='0' BOTTOMMARGIN='0' LEFTMARGIN='0' RIGHTMARGIN='0' BGCOLOR='#000000'>
  {&INCLUDE_(header)&}
  {&INCLUDE_(main_content)&}
  {&INCLUDE_(footer)&}
 </BODY>
</HTML>

So I need to pull all of the {&*&} tags out. Then return all of the tags that are on the page in any array.

Here's the code I'm working with:

<?php
$file = "<HTML>
 <HEAD>
  <TITLE>{&PAGE_TITLE&}</TITLE>
 </HEAD>
 <BODY TOPMARGIN='0' BOTTOMMARGIN='0' LEFTMARGIN='0' RIGHTMARGIN='0' BGCOLOR='#000000'>
  {&INCLUDE_(header)&}
  {&INCLUDE_(main_content)&}
  {&INCLUDE_(footer)&}
 </BODY>
</HTML>";
$pos = 0;
while ($pos < strlen($file))  {
    $pos =  strpos($file,"{&",$pos);
    $pos+1;
    $lastpos = strpos($file,"&}",$pos);
    $tag = substr($file,$pos,$lastpos-$pos);
    $pos = $lastpos+1;
    $tagpos = $pos;
    $pos = strpos($file,"{&",$pos);
    $tag = substr($file,$tagpos,$pos-$tagpos);
    $tags[] = trim($tag);
    $pos = $lastpos+1;
}
echo count($links);
?>

Now I know I'm heading in the wrong direction with this, but the question is, which way is the right direction.

Any help is greatly appreciated.

Hi,

Unless I am absolutely wrong here.. can't you just use:


<HTML> 
<HEAD> 
  <TITLE><? $PAGE_TITLE ?></TITLE> 
</HEAD> 

<BODY TOPMARGIN='0' BOTTOMMARGIN='0' LEFTMARGIN='0' RIGHTMARGIN='0' BGCOLOR='#000000'> 

<? INCLUDE(header.php) ?>
<? INCLUDE(main_content.php) ?>
<? INCLUDE(footer.php) ?>

</BODY> 
</HTML>";

Well there's going to be alot more to a page then that. I also need the template files pretty simple. It's hard to explain exactly. Thank you for your post though, I do appreciate it.

you will probably need
preg_replace()

but im not good with regex..
